| 説明 | During both the First World War and the Second World War, Inchcolm was part of the defences of the Firth of Forth. Inchcolm was the HQ of what were called in the First World War the 'Middle defences', the main element of which was a continuous anti-submarine and anti-boat boom across the river. The defences were intended to protect the naval anchorage between Inchcolm and the Forth Rail Bridge (as there was no longer room above the bridge to moor all the ships based in the Forth). The defences of Inchcolm were significantly strengthened in 1916-17 when it was decided to move the Grand Fleet from Scapa Flow to the Forth. As part of these works 576 Cornwall Works Company, Royal Engineers, built a tunnel under the hill at the east end of the island, to link a new battery of guns to their magazine, on the protected side of the island. The tunnel is dated 1916–17. The First World War engine house (which powered the defence searchlights) was adapted in the 1930s as a visitor centre, which it is still used by Historic Scotland. The island was re-occupied in 1939, when the anti-submarine and anti-boat boom was once again laid across the estuary. Many features of both wars survive, including a First World War drying hut, and the brick building in which the staff of the NAAFI lived in the Second World War. |
